Definitions

  • the injecting operation of monomer has come to be automated, where it is difficult to inject the monomer into the mold if the viscosity of the monomer is lower than a predetermined value.
  • Manual injection allows injection of more viscous monomers than the monomers that can be injected by automated injection. However, it still is difficult to be injected into the mold when the viscosity of the monomer is lower than a predetermined value.
  • the materials mentioned as (a), (b) and (c) in the above are blended in the tank and are subjected to the preliminary polymerization step, the cooling step and the deaeration step.
  • the viscosity of the composition in the tank can be constantly measured. Then, the viscosity of the composition in the tank is displayed on a display device for displaying a measured value detected by the viscometer.
  • the viscosity of the composition in the tank can be constantly monitored, thus achieving the above advantages.
  • the added amount of the compound (b) is 50 parts by mass or more and 99 parts by mass or less, which is preferably 50 parts by mass or more and 95 parts by mass or less, more preferably 60 parts by mass or more and 90 parts by mass or less, further preferably 65 parts by mass or more and 85 parts by mass or less, and especially preferably 70 parts by mass or more and 80 parts by mass or less when the total of the compound (a) and the compound (b) is 100 parts by mass.
  • phosphines include trimethylphosphine, triethylphosphine, tri-iso-propylphosphine, tri-n-butylphosphine, tri-n-hexylphosphine, tri-n-octylphosphine, tricyclohexylphosphine, triphenylphosphine, tribenzylphosphine, tris(2-methylphenyl)phosphine, tris(3-methylphenyl)phosphine, tris(4-methylphenyl)phosphine, tris(diethylamino)phosphine, dimethylphenylphosphine, diethylphenylphosphine, dicyclohexylphenylphosphine, ethyldiphenylphosphine, diphenylcyclohexylphosphine, and chlorodiphenylphosphine.
  • tertiary sulfonium salts include trimethylsulfonium bromide, triethylsulfonium bromide, tri-n-butylsulfonium chloride, tri-n-butylsulfonium bromide, tri-n-butylsulfonium iodide, tri-n-butylsulfonium tetrafluoroborate, tri-n-hexylsulfonium bromide, tri-n-octylsulfonium bromide, triphenylsulfonium chloride, triphenylsulfonium bromide, and triphenylsulfonium iodide.
  • tin halides include tin tetrachloride, diethyldichlorosilane, dimethyltin dichloride, trimethyltin chloride, ethyltin trichloride, diethylgetin dichloride, triethyltin chloride, propyltin trichloride, dipropyltin dichloride, tripropyltin chloride, n-butyltin trichloride, di-n-butyltin dichloride, tri-n-butyltin chloride, tert-butyltin trichloride, di-tert-butyltin dichloride, tri-tert-butyltin chloride, amyltin trichloride, diamyltin dichloride, triamyltin chloride, octyltin trichloride, dioctyltin dichloride, trioctyltin
  • amines include those described in the section of the epoxy compounds and which were given as examples of the object raw material reacted with epihalohydrins.
  • the viscosity of the reacting composition can be always measured by the viscometer 120 immersed in the reacting composition (or material) in the tank 110. Accordingly, the second control unit 152 monitors the viscosity displayed on the display device 123 (step S4) and continues the step S3 until the viscosity reaches to a predetermined value.
  • the predetermined viscosity is 50 mPa ⁇ s.
  • a refractometer may be additionally attached to the tank 110. Accordingly, both of the viscosity and refractive index can be monitored, thus allowing production of mass-producible and high quality products.
